Automate OCR using Adobe Acrobat Pro's Action Wizard
Use the built-in Action Wizard in Acrobat Pro to run OCR automatically across multiple files in a specified folder without writing any code.
Acrobat Pro includes a powerful batch processing tool called Action Wizard. It allows users to string together multiple commands, such as applying text recognition, and execute them on an entire directory of files at once.
Open Adobe Acrobat Pro. Go to the 'Tools' menu and select 'Action Wizard' from the list of available features.
Click on 'New Action' in the toolbar. In the 'Choose tools to add' pane on the left, expand 'Recognize Text', select 'In Multiple Files', and click the '+' icon to add it to your action steps.
Under 'Files to be Processed' on the right side, click 'Add Folder' and browse to the directory containing the scanned PDFs you want to process.
Click 'Save' and give your action a clear name, such as 'Batch OCR'. To automate the OCR process, simply click on this new action in the Action List and select 'Start'.
Implement Automated OCR via Adobe PDF Services API
For enterprise-level automation or integration into custom applications, use Adobe's dedicated PDF Extract API.
